HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 731, 768 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 338, 731, 768 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 338, 731, 768 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 338, 731, 768 is 1.
HCF(338, 731, 768) = 1
HCF of 338, 731, 768 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 338, 731, 768 is 1.
Highest Common Factor of 338,731,768 is 1
Step 1: Since 731 > 338, we apply the division lemma to 731 and 338, to get
731 = 338 x 2 + 55
Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 55 and 338, to get
338 = 55 x 6 + 8
Step 3: We consider the new divisor 55 and the new remainder 8, and apply the division lemma to get
55 = 8 x 6 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 338 and 731 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(55,8) = HCF(338,55) = HCF(731,338) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 768 > 1, we apply the division lemma to 768 and 1, to get
768 = 1 x 768 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 768 is 1
Notice that 1 = HCF(768,1) .
